IMPROVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent No. 135,977, dated February18, 1873.

, nest Von J enisen, bearing date April 11, 1871,

and assigned by him to the JENISEN LUBRI- oAToR COMPANY: Also, I haveassigned my present invention to the said J ENIsEN LUBRI- -GATORCOMPANY, by an instrument under my hand and seal bearing even date withthe application.

My invention consists mainlyin the employment of a box or reservoirconstructed of thin metal, in which the oil and lubricating-pad areplaced. The innerend of the box is cut away for the working ofthe axle,and a semicireular ange is fitted over the lower half of the opening ofthe axle-box proper. Slots are made in the side of the box so as toadmit the gate or spring-board for the end of the axle, and a beveledgate shuts down upon the entire end of the axle-box, which excludes thedust and water from the interior, as will hereinafter more fully appear.

Referring to the drawing, Figure 1 represents a longitudinal section ofmy invention. Fig. 2 is a transverse section; Fig. 3, a per- Spectiveview of the reservoir.

A represents a rectangular box, constructed preferably of thin metal,whose sides, when in position, extend upward to the brasses or bearingof the axle'B. The inner end is cut away for about one-half the diameterof the axle, and a semicircular iiange or thin edge, C, iits over thelower half of the opening in the box proper, on which the axle plays, inwhich position it is held by the lugs or points C'. By this means,

the oil or lubricating material which would naturally run oft from theaxle and be lost is returned intothe box to ,be drawn up again andutilized. The outer end of the reservoir extends to near the end of theaxle-box, and is on a horizontal plane with its sides. Vertical slots DD are made in the sides to admit the gate or spring-board E for the endof the axle, which corresponds in width to the space between the lugs 1)of the axle-box. A closelyfitting gate, F, with circular top, shuts intothe end of the axle-box, in which position it is held by a set-screw, F.When the gate is raised, it will be seen that the end of the axle-box isflush with the door, so that the oil-reservoir can be removed like adrawer. By reference to this invention it will clearly be seen that butlittle, if any, of the oil can escape by slopping over or otherwise, asthe sides of the reservoir or lining extend up to the bearings of theaxle, and the outer end is on a plane with the sides, andthe inner endssurround a sufficient portion of the axle to prevent escape in thatdirection.

It will also be furthermore observed that this invention is almostindispensable to the successful operation of that class of devices whichdepend largely upon pads held by springs to eii'ect lubrication.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The lugs or points C C for holding the box when in position,substantially as set forth.

2. The axle-box i described, having the outside case with sliding coverF, removable reservoir A having slots D D and dan ge C', and gate orspring-bearer E, all constructed and arranged as described, for thepurpose set forth.

In witness whereof I have hereunto set my hand and seal.
